Malva sylvestris, Punica granatum, Amygdalus communis, Arnebia euchroma and Scrophularia deserti are important medicinal plants in Iranian traditional medicine (Unani) whose have been used as remedy against edema, burn, and wound and for their carminative, antimicrobial and anti-inflammatory activities. The ethanol extracts of M. sylvestris and P. granatum flowers, A. communis leaves, A. euchroma roots and S. deserti stems were used to evaluate the burn healing activity in alloxan-induced diabetic rats. Burns were induced in Wistar rats divided into nine groups as following; Group-I: normal rats were treated with simple ointment base (control), Group-II: diabetic rats were treated with simple ointment base (control), Groups-III and -VII: diabetic rats were treated with simple ointment base containing of extracts (diabetic animals), Groups VIII: diabetic rats were treated with simple ointment base containing of mixed extracts, Group-IX: diabetic rats received the standard drug (Silver Sulfadiazine). The efficacy of treatments was evaluated based on wound area, epithelialization time and histopathological characteristics. Wound contraction showed that there is high significant difference between the different groups (p<0.001). At the 18th day, A. euchroma, S. deserti, A. communis and mixed extract ointment treated groups healed 80-90%. At the 9th and 18th days the experiment, the best results were obtained with A. communis and standard drug, when compared to the other groups as well as to the controls. It may be concluded that almond leaves (sweet and bitter) formulated in the simple ointment base is effective in the treatment of burns and thus supports its traditional use.

We examined the cholesteryl ester transfer protein (CETP) gene TaqI intron 1 B1/B2 polymorphism and the -629A/C CETP promoter polymorphism in respect to high-density lipoprotein cholesterol (HDL-C) in a healthy Iranian population taken from the Tehran Lipid and Glucose Study (TLGS). The relationship between CETP activity and HDL-C level was also determined along with body mass index, blood pressure and tobacco smoking status. PCR-RFLP used to amplify a segment of the CETP intron 1 TaqI (B2/B1) polymorphism from 1021 individuals and we selected 345 individuals from the lowest, middle and highest HDL-C deciles and investigated the -629A/C polymorphism. We also evaluated the CETP activity of 103 of these individuals, each with at least one homozygous allele. The presence of the TaqI B2 and -629A/C A alleles were significantly associated with increased HDL-C levels (B2B2 = 1.19 ± 0.31 mmolL-1 vs. B1B1 = 1.01 ± 0.2 mmol L-1 for p < 0.001; AA = 1.15 ± 0.41 mmol L-1 vs. CC = 0.95 ± 0.28 mmol L-1 for p < 0.001) and decreased the CETP activity (B1B1 = 67.8 ± 8.9 pmol L-1 vs. B2B2 = 62.6 ± 9.6 pmol L-1 for p < 0.01; CC = 68.6 ± 8.4 pmol L-1 vs. AA = 62.7 ± 9.7 pmol L-1 for p < 0.002). The frequencies were 0.382 for the TaqI B2 allele and 0.462 for the -629A/C A allele, with linkage disequilibrium analysis giving D = 0.0965 and D' = 0.4695. We demonstrated that the TaqI B1 and B2 alleles and the -629A/C A and C alleles were in linkage disequilibrium in our population and that there was a significant association between the B2 and A alleles and high HDL-C levels and low CETP activity. Linkage disequilibrium between the TaqI A and B2 alleles also detected.
